Subject: satapi auto sense begun again
Date: 07 Jun 2004 18:13:34 -0600 [thread overview]
Message-ID: <1086653614.3410.30.camel@patibmrh9> (raw)
Jeff G:
Can you suggest a specific thing for me to try or to study, to make
progress?
Where I left this work was that we can issue an unsolicited PIO op
xA0:03 "REQUEST SENSE" (for a multiple of four bytes) immediately after
op xA1 "IDENTIFY" ... but later we cannot inject even a PIO op x00
"NOP".
I imagine somehow interrupt handling is the issue?
